My wife and I had an ungrounds pool installed last year. 18x36 with an 8 foot deep end. Over the winter I put a utility pump in it to draw some water out after the level got to high due to rain. Well I fell asleep and pumped out to much water. Now I have taken off my cover and the deep end of the liner is floating slightly off the bottom. It is extremely difficult to get anyone out to help this time of year so I am wondering if I should attempt to pump the water behind the liner myself. If I wait on a service call can I go ahead and run my pump and vacuum so the pool is open once they arrive?
